There's no magic number of trials you need to do. You do n trials, and you get the correct answer, say, m times. Then you use the binomial (in this case) distribution to determine the probability p that you obtained that result, or a more extreme one, by random guessing. 1-p is then the confidence with which you can reject the hypothesis that you were guessing. That sounds more complicated than it is, but there you have it. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=38258 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
